Syzygium cumini (L.) commonly known as jamun belongs to the Myrtaceae family. The aim of the present study includes phytochemical investigation and in vitro anti-oxidant capacity of various crude extracts from the bark of syzygium cumini (L.) by various anti-oxidant assays namely DPPH (2, 2-diphenyl-1-picrylhydrazyl), Nitric Oxide (NO) and Hydrogen peroxide (H 2 O 2 ). Chloroform Ethyl acetate (EA) and Methanolic (MeOH) extracts of S. cumini gave positive results for steroids, alkaloids, tannins and flavonoids. The scavenging ability of chloroform, ethyl acetate and methanolic extracts along with standard Ascorbic acid were evaluated between the range of 20μg/ml to 300μg/ml using DPPH anti-oxidant assay and the IC 50 values were found to 41μg/mL, 57 μg/mL, 53 μg/mL and 6.1 μg/mL respectively. To prove further its anti-oxidant activity, they were evaluated using NO and H 2 O 2 antioxidant assays.
